ProtonVPN was developed by the team behind ProtonMail to provide a secure, privacy-respecting way to browse the internet. Built with privacy-first principles and based in Switzerland — a country with strong privacy laws — ProtonVPN positions itself as a choice for users who want both technical protections and a company commitment to keeping no records of what they do online. Security and privacy features are at the core of ProtonVPN. The service supports modern VPN protocols such as WireGuard, OpenVPN, and IKEv2, and uses industry-standard encryption (AES-256) with perfect forward secrecy to protect session keys. ProtonVPN offers a kill switch and DNS leak protection so traffic does not escape the tunnel if connectivity drops. For users who want extra hardening, Secure Core routes traffic through multiple servers in privacy-friendly countries before it exits to the wider internet, reducing the risk of network-level surveillance. ProtonVPN also supports connecting to the Tor network through a built-in “Tor over VPN” option for easy access to .onion services without a separate Tor browser. Transparency is another selling point: ProtonVPN’s desktop and mobile apps are open-source, allowing experts to inspect the code, and the company has invited independent security audits. Their no-logs policy means ProtonVPN does not retain activity logs, connection timestamps, or IP addresses tied to user activity. Practical aspects include a global server network with locations optimized for speed, streaming, and P2P/torrenting. ProtonVPN offers a free tier with limited servers and speed, which is useful for testing or light everyday use. Paid plans expand server access, unlock faster speeds with WireGuard, enable Secure Core and Tor features, and allow more simultaneous connections. ProtonVPN works across Windows, macOS, Linux, Android, and iOS, and can be configured on routers. Use cases range from securing Wi‑Fi on public networks and preventing ISP tracking to bypassing geo-blocks for streaming and maintaining anonymity when using P2P networks. Downsides to consider: top-tier features require a paid subscription, and Secure Core multi-hop routing can reduce throughput compared with single-hop connections. Tips: choose WireGuard for best speed, enable the kill switch, try the free plan before upgrading, and pick a server geographically close to you for lower latency unless you specifically need privacy-oriented routing. Overall, ProtonVPN is a solid choice for users who prioritize privacy, transparency, and a reputable company standing behind their VPN service.
